APPARATUS FOR SUSTAINING PUNCHlNG-BAGS.

SPEGIFICATION forming part of Letters Patent No. 519,918, dated May 15, 1894.

' Application filed June 2,1893. Serial No. 476,410. (no model.)

To all whom it may concern:

Be it known that I, JOHN PARKER MAC- LEARN, a citizen of the United States of Amer- 10a, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have lnvented certain new and useful Improvements in Apparatus for Sustaining, Exercising, or Punching Bags, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in exerclsing machines, and consists of the novel construction of the mechanism of the same as hereinafter described.

In the drawing which represents a perspective View of my invention, A designates a base preferably of cast iron and of sufiicient weight to maintain its position without being fastened to the floor, this requires no work in fitting other than placing set screw a, the socketb being formed in the casting; second, the upright spiral spring B which is cheaply made of cold roiled Bessemer steel spring wire about three-eighths inch diameter and coiled to about one and one-half inch outside diameter, the spring being about two feet in length; third, of the extension piece O about two feet long with its surmounting cap of leather, for this I have used a piece of bamboo cane and find that it combines the requisite strength with lightness. The leather cap is for protection to the ball against the end of the stick, the ball resting on the leather and same being fastened to the stick by winding with cord or any of the methods which can be used. About four inches below the leather cap a knob E is formed on the stick by winding with twine, the use of which will be explained farther on.

large to insert the rubber bag, or bladder, with air exhausted, after which it can be blown up, the bag or bladder is made the same as those used for foot balls and has a projecting tube through which air .is forced into the bag when necessary. The uses of these different parts are as follows: The spring B is inserted into socket b of base A and held firmly by set screw a, the extension 0 is inserted into upper end of spring B and held in place by driving a pin through the interstices of the spring. The rubber ball with air ex hausted is forced into the caseD and is then blown full of air forming with the case an elastic rebounding sphere, then by means of the flaps or ears of case D the ball or sphere is firmly fastened to. the upright stick, the in: side ball resting on the leather cap before mentioned and the ears wound to the stick with twine below the knob, thus holding the punching bag securely on its flexible statf.

The bag upon being struck a sharp blow,

causes the spring B to be deflected according to the force of blow and immediately rebounds to be struck again and again. The spring not only furnishes a resilient standard, but supports the extension without the employment of separate springs, and the standard is adapted to swing in every lateral direction so that exercising may be accomplished from any point of the ball or head.

hat I claim, and desire to secure by Letters Patent, is-

An exercising machine consisting of a base provided with a socket, an upright coiled spring with its lower end connected in said socket, a vertical extension piece secured in the upper end of said spring, a casing attached to the upper end of said extension piece, and a ball in said casing, said parts being combined, substantially as described.-
